SVG Minifier
Strip all comments, XML declarations, and unnecessary whitespace from SVG markup to produce the most compact valid output.
What is SVG Minification?
SVG minification removes all non-essential characters - whitespace between elements, line breaks, indentation, XML comments, and XML processing instructions - to produce the smallest valid SVG document. The visual output is byte-for-byte identical to the original; only formatting characters are stripped.
Unlike full optimization (which restructures the SVG), minification is a safe, non-destructive operation. It does not modify path data, attributes, or element structure. It is ideal when you need predictable output without risking any visual regressions.
Minification vs Optimization
| Feature | Minifier | Optimizer |
|---|---|---|
| Removes whitespace | Yes | Yes |
| Removes comments | Yes | Yes |
| Modifies path data | No | Yes |
| Removes editor metadata | No | Yes |
| Typical size reduction | 5-20% | 20-70% |
| Visual regression risk | None | Very low |
Common Use Cases
Inline SVG in HTML
When embedding SVG directly in HTML markup, minified SVG reduces page weight and keeps the HTML source readable by collapsing multi-line SVG into a single compact element.
Data URI Generation
Minify SVG before encoding it as a data URI. Whitespace in SVG data URIs adds URL-encoded characters that bloat CSS files. A minified SVG produces a significantly shorter encoded string.
